Connecting apparatus for cartridge of learning device

Abstract

Enclosed is a connecting apparatus for a cartridge of a learning device for connecting a cartridge having software to a main body of the learning device. When a user only rotates the cartridge to a supporting frame direction in such a condition that the cartridge is inserted, a connector supporting holder having the connector moves to an upper direction. Accordingly, a printed circuit board of the cartridge connects to the connector exactly. Consequently, the connecting failure between the cartridge and the connector can be prevented and the inserting and withdrawing operation of the cartridge are easily executed because the inserting and withdrawing operation of the cartridge are executed before and behind the connecting operation of the connector.

What is claimed is: 
     
       1. A connecting apparatus for connecting a cartridge enclosing a printed circuit board to a main body of a learning device, comprising: a supporting frame installed on the main body of said learning device for supporting a rear face of said cartridge;   a subsidiary frame installed on a lower side of said supporting frame, said subsidiary frame having an inserting groove formed on an upper portion for inserting the cartridge;   a cartridge holder that holds the cartridge in said subsidiary frame; and   a connector supporting holder for connecting or disconnecting a connector to or from a printed circuit board of the cartridge by ascending and descending in an inner portion of the cartridge holder as a function of the rotation of the cartridge holder, said connector supporting holder supporting said connector.   
     
     
       2. The connecting apparatus of claim 1, wherein a torsion spring biases said cartridge holder to rotate in a direction withdrawing the cartridge from said supporting frame. 
     
     
       3. The connecting apparatus of claim 2, wherein said torsion spring is fixed to an inner side of said subsidiary frame and regulated by a stopper formed at a side of said cartridge holder. 
     
     
       4. The connecting apparatus for cartridge of the learning device of claim 1, wherein a roller is installed on one lower portion of said connector supporting holder and a guide rib is formed in an inner portion of said subsidiary frame and said guide rib guides said roller when said cartridge rotates so that the connector supporting holder ascends in said cartridge holder further securing said connector and said printed circuit board. 
     
     
       5. The connecting apparatus of claim 4, wherein a coil spring is installed on a guide shaft, said coil spring biases said connector supporting holder in a downward direction of said cartridge holder. 
     
     
       6. The connecting apparatus of claim 1, wherein a locking knob detachably engages an upper end portion of said cartridge and a torsion spring biases the locking knob to prevent said cartridge from separating from said supporting frame. 
     
     
       7. A cartridge securing system, comprising: a cartridge having a first end, a first major surface, and a second end and enclosing a printed circuit board that is accessible via an opening in said second end;   a frame having a second major surface and capable of supporting said cartridge with said first major surface abutting said second major surface;   a clip disposed proximate to a first edge of said second major surface for securing said first end of said cartridge against said frame;   a device disposed along a second edge, opposite from said first edge, of said second major surface for securing said second end of said cartridge, said device comprising: a housing bearing a slot that receivably engages said second end of said cartridge;   a sleeve coupling extending inward from said housing and surrounding said slot;   a shaft slidably engaged with said sleeve coupling; and   a connector mounted on said shaft and contained within said sleeve coupling, said connector engageable with said printed circuit board in said cartridge;     said cartridge securely engageable with said frame while said first end of said cartridge is engaged with said clip and said second end of said cartridge is engaged with said device to bring said printed circuit board into engagement with said connector.   
     
     
       8. The cartridge securing system of claim 7, further comprising: an elastic member biasing said shaft in a first direction away from said slot causing said shaft to protrude from said sleeve coupling;   a roller attached to said shaft;   a rib attached along an inner surface of said housing; and   said rib abutting said roller while said first major surface is being brought into contact with said second major surface, thus causing said shaft to move in a second direction, opposite from said first direction, and further securing said printed circuit board with said connector.   
     
     
       9. The cartridge securing system of claim 8, further comprising a second elastic member biasing said sleeve coupling to rotate said cartridge away from said frame and separate said first major surface from said second major surface. 
     
     
       10. The cartridge securing system of claim 9, further comprising a panel covers said slot in said housing and rotates to expose said slot when said second end of said cartridge abuts said panel. 
     
     
       11. The cartridge securing system of claim I0, further comprising: a channel in said sleeve coupling; and   a latch protruding from a distal end of said shaft and engaging said channel.   
     
     
       12. A cartridge securing system, comprising: a cartridge having a first end, a first major surface, and a second end and enclosing a printed circuit board that is accessible via an opening in said second end;   a frame having a second major surface and capable of supporting said cartridge with said first major surface abutting said second major surface;   a clip disposed proximate to a first edge of said second major surface for securing said first end of said cartridge against said frame;   a device disposed along a second edge, opposite from said first edge, of said second major surface for securing said second end of said cartridge, said device comprising: a housing bearing a slot that receivably engages said second end of said cartridge;   a sleeve coupling extending inward from said housing and surrounding said slot;   a shaft slidably engaged with said sleeve coupling;   a connector mounted on said shaft and contained within said sleeve coupling, said connector engageable with said printed circuit board in said cartridge;   an elastic member biasing said shaft in a first direction away from said slot causing said shaft to protrude from said sleeve coupling;   a roller attached to said shaft;   a rib attached along an inner surface of said housing; and   said rib abutting said roller while said first major surface is being brought into contact with said second major surface, thus causing said shaft to move in a second direction, opposite from said first direction, and further securing said printed circuit board with said connector; and     said cartridge securely engageable with said frame while said first end of said cartridge is engaged with said clip and said second end of said cartridge is engaged with said device to bring said printed circuit board into engagement with said connector.   
     
     
       13. The cartridge securing system of claim 12, further comprising a second elastic member biasing said sleeve coupling to rotate said cartridge away from said frame and separate said first major surface from said second major surface. 
     
     
       14. The cartridge securing system of claim 13, further comprising a panel covers said slot in said housing and rotates to expose said slot when said second end of said cartridge abuts said panel. 
     
     
       15. The cartridge securing system of claim 14, further comprising: a channel in said sleeve coupling; and   a latch protruding from a distal end of said shaft and engaging said channel.
